Identification is difficult due to similar species. Colour is highly variable, from yellow to almost black (possibly becoming darker with age). The distinguishing feature is a single pair of 'teeth' on the thickened apical edge of the manubrium as illustrated.
- Ocelli C-D-E aligned (= genus Isotoma)
- One pair of manubrial teeth.
Confirmation requires microscopic proof of presence of one pair of manubrial teeth.
Moist habitats, under stones and logs, in leaf litter and moss etc.
All year round.
Widespread and fairly frequent in Britain.
Status in Leicestershire and Rutland not known.
